Abstract
Disclosed is a display device integrated with touch screen. The display device has a reduced bezel and an enhanced aesthetic design. Left and right bezels of a panel are reduced, thus increasing an aesthetic design. A driving circuit that generates the touch driving signal is built into the panel, thus decreasing the size of the touch IC and the manufacturing cost.
